The Bosch Rexroth B.RUN. BLOCK NRFG KWD-035-FNS-C0-H-0 (R200139314) is a high-precision ball runner block designed for linear motion applications. This particular model is crafted from Resist NR, making it suitable for use in environments such as the packing industry and food industry subsectors where corrosion resistance is crucial. The runner block features an FNS format, indicating a flanged width, normal length, and standard height configuration. Its body and all steel components are constructed from corrosion-resistant steel compliant with DIN standards. This NRFG ball runner block comes in preload class C, meaning it is preload-free, and boasts an accuracy class H for high precision. It does not include a ball chain, preservation, or initial lubrication to allow for customization based on application requirements. The attachment elements are absent on both the left front reference edge and right front reference edge. The runner block has an overall length of 70 mm and provides excellent dynamic characteristics with the same high load ratings in all four main directions of loading. It can be used with all SNS ball guide rails. One of its standout features is its long-term lubrication capability that can extend over several years, facilitated by lube fittings with metal threads on all sides. Interchangeability is limitless within each accuracy class as this ball guide rail system can be combined with any ball runner block version. The design maximizes system rigidity through a preloaded O-arrangement and includes end-face fastening threads for various attachments. The integrated all-around sealing and optimized entry-zone geometry ensure minimal variation in elastic deflection while providing smooth and quiet operation. Additional rigidity under lift-off and side loading conditions is achieved through two extra mounting screw holes at the center of the block. This product's dynamic load capacity C and other load capacities are determined based on a nominal travel distance as per DIN ISO standards, ensuring reliability for various linear motion tasks.
